For the sturgeon species, the situation has deteriorated significantly since the last assessment of the IUCN in 2010, with the change being most dramatic in Europe and Asia.

Inland waters are becoming increasingly saline. An international research team with Stella Berger, Jens Nejstgaard from IGB and the AQUACOSM-plus consortium published an analysis of the present status of knowledge and propose a new research agenda on the topic.

The International Society of Limnology (SIL) is celebrating its 100th anniversary with an international conference in Berlin. This is being hosted by IGB. 

Low-growing species such as stoneworts were last sighted in the Müggelsee over a century ago. Now, after 20 years of intensive mapping and diving surveys, not just one but three of these desirable species of underwater vegetation have been found.

 Urbanization introduces large amounts of nutrients, chemical pollutants and antimicrobial products, and thereby changes the makeup of the microbiome by favouring groups of bacteria that contain human pathogenic bacteria, with yet unknown consequences for ecosystem functioning and human and animal health.

IGB scientist Michael Hupfer has received an honorary professorship for "Aquatic Biogeochemistry" at BTU Cottbus-Senftenberg. 

The Prussian carp or Gibel carp is considered one of the most successful invasive fish species in Europe. Its ability to reproduce asexually gives it a major advantage over competing fish. An international research team has for the first time described the complete genome of the Prussian carp. This also provides a much better understanding of its unusual reproductive method and to improve its management.

Since 1996, the Albrecht-Daniel-Thaer-Förderpreis has been awarded for special doctoral achievements and degrees at the Thaer-Institute of Agricultural and Horticultural Sciences at the Humboldt-Universität zu Berlin. Philipp Czapla received the award for his outstanding Master's degree in the M.Sc. Fish Biology, Fisheries and Aquaculture programme, which is co-led by IGB.
